nature #282 Rien Poortvliet (1932-1995)

The picture has something of this: dark, fog, sky, landscape, soil, dawn, outdoors, silhouette, parchment, tree, nature, mist, paper, weather, storm, light, sepia.
Perhaps it’s a painting of a rainbow in a cloudy sky with a bird sitting on a fence in the foreground and a bird on a tree.
